Be it known that I, JOSEPH MCCOY, a citizen of the United States, residing at Independence, in the county of Jackson, in the State of Missouri, have invented certain new and useful Improvements in Cistern Cut-Offs, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings,which form part of this specification.

My invention relates to certain new and useful improvements in cistern cut-offs, and is v designed to provide an automatic cut-off in that class of cistern pipes or spouting in which thepipe leading from .the roof branches bel fore reaching the cistern, one branch leading to the cistern and the other to the sewer or other Wasteway; and my invention consists in certain features of novelty hereinafter described, and point-ed out in the claim.

Figure I represents a cistern-pipe of the v.class mentioned provided With my improvements, the pipe being shown in cross-section to show the arrangement thereof. Fig. II represents a view of the top of the bucket.

l Fig. III represents a View of the bottom of the same. Fig. IV represents a view of a portion of the cut-off, showing the cup therein.

Fig. V represents a front elevation showing a diiferent arrangement `of the Weight and Water vessel with relation to the vaxial line of lthecut-off. Fig. VI represents a side elevation of the device asshown in Fig. V with the cut-od removed from the spouting. Fig. VII represents a side elevation of the device as shown in Fig. V. Fig. VIII represents a side elevation of the device as shown in Fig., VL

Similar numerals refer to similar parts throughout the several views.

p 1 represents the pipe leading from the roof,

having the branch `2, leading to the cistern,

and the branch 3, leading to the sewer or other i wasteway.

In the throat formed by the union of the branches with the roof-pipe and substantially -in line with the point of bifurcation is mounted on the pivot 4. the switch or cut-off 5, so arranged that when tilted in one direction it will close the pipe leading into the cistern and convey the Watercoming down through the pipe 1 into the sewer-pipe, and when tilted in the opposite direction it will close the pipe leading to the sewer andconv'ey4 thewatl' into the pipe leading into the cistern(` A'Ifo "efe fect this tilting automatically-sothat when the rain comes the cut-off will be turned to lead Water into the cistern and when the'ain is over the cut-off will be returned @to posi'.-

tion to lead the Water to the sewer, is'the fobQ ject of my invention. To do this, I suspend from the cut-off on one side yof the plane of the axis the bucket 6.

In the cut-off Ifpro` vide a cup 7, and on the under 'side ofthe position yto close the pipe leading to the cisi tern the cup will be in position to intercept and catch some part of the water coming down from the roof-pipe, whichr Water will pass through the funnel and empty into the bucket. On the opposite side of the plane of the aXis'I suspend the weight 9, the relation of the Weight being such that when the bucket is empty the Weight is heavier than the bucket and will overbalance it and cause the cut-off to assume the positionshown in heavy lines in Fig. I, turning the water out of the cistern and into the sewer-pipe; but when the bucket becomes filled with Water it is heavier than the weight and overhalances it and causes the cutoff to assume the position shown in dotted lines in said figure, turning the flow of Water into the cistern and cutting off the sewer-pipe. In this position the bucket will swing partly into the pocket or recess 10, formed in the side of the pipe, where it will not interfere so much with the free ioW of the Water through the pipe, but will yet receive suiiicient Water to keep it filled during the continuation of the rain and consequent flow of water. When 14 shall slide, respectively, in the elongated IOO 1.a ceases;

Ways l5 and 16 along,r the under side of the cut-off as the cut-off changes its position, and thus giving an increased leverage to the weight or bucket as the one or the other occupies the lower position and rendering the device in a degree more stable.

As shown in Figi. V' to VII, without departing from the principle of my invention, instead of connecting the Weight and vessel directly to the cnt-off, as shown in Fig. l', a grooved wheel or sheave 2O maybe mounted on the extended axis or pivot 4 of the cut-oit' and the Weight 9 suspended therefrom on one side by a cord or cable 21, passing over the sheave and secured thereto on the opposite side, and the bucket 6, suspended from said sheave on the other side by a cord or cable 25, passing,r over the sheave and secured thereto on the opposite side. In the construction a lip or cup 22 is formed on the inside of the spout above the branches, arranged to catch the water as it comes down the spout, and from said lip or cup the water is carried by the pipe 23, communicating therewith, into the bucket, and the bucket may be provided with a conical-shaped cover 21k to prevent leaves and trash blowing therein, and the pipe may be extended a distance into the bucket to insure the Water entering the same. By this construction and arrangement is pro vided a cnt-off purely automatic in its action in closing and opening the pipe leading to the cistern, being governed and controlled en tirely by the rainfall and requiring no attention after being once pnt in place. Among its principal advantages are that, requiring no attention, the beneiit oi the rainfall in `filling the cistern will not be lost through neglect to turn the cut-off in its proper direction, and, again, the bucket requiring' a certain time to lill and operate the cut-off, time will be given for the rainfall to wash the dust and dirt accumulating on the roof into the sewer before the Water is turned into the cistern, and thus the cistcrn is kept free from these impurities. The bucket may bc kept open .at the top, or it may be covered by the lid 18, having the opening 19 therein, so that it will not be iilled so rapidly, but sufficient time will be allowed in which the impurities from the roof will be Washed off and carried into the Waste-pipe, the relation also between the holes in the lid and the holes in the bottom of the bucket being such that the water will run into the bucket faster than it runs out.

Having thus described my improvements, whatl claim, and desire to secure by Letters Patent, isn- The combination with a pivotcd cutoff in a cistern-pipe of a weight connected with said cutoff, a vessel connected with said cnt-oil and means for filling and emptying said vessel, the construction and arrangement being such that as said cut-oit changes its position the relation of said Weight and vessel to the axis will. correspondingly change, substan-
